Please note visa support letters are issued via email by PDF and the original is mailed to your current postal address.

Hotel Information:

The organizers of the conference have pre-selected hotels for the benefit of its participants. These rooms will be allocated to participants free of any handling fee - please use the online hotel booking form at https://ebms.univie.ac.at/iEBMS/reg/reg_p1_form.aspx?oc=10&ct=013&eventid=18097.
